. a specification, reference being had therein to the accompanyingdrawings.

The invention relates to a construction of corner, being moreparticularly designed for use in carriage construction.

In the drawings, Figure 1 is a perspective view of the inverted cornerwith the metallic angle detached. Fig. 2 is a bottom plan view of acorner, and Fig. 3 is a section on line :10 0c of Fig. 2.

In the present state of the art carriagebodies are usually formed oflight construction, and on account of the thinness of the boards used itis difficult to join them so as to provide the necessary strength.Various constructions have been made in which the corner of the box isstrengthened by metallic angle-irons; but these are usually arranged tooverlap the sides of the box, so as to avoid danger of splitting thethin side boards. In the present construction the corner is strengthenedby a metallic angle, which is applied merely to the bottom of the boxand is not exposed to view at the sides, said angle being of peculiarconstruction, so as to prevent danger of splitting the wood by thesecuring devices.

As shown, A and B are the two adjoining sides of the body, and O is thesill, the end of which fits the corner between the sides. This sill isusually made of hard wood, whereas the side panels are of soft wood andare very thin. D is a suitable corner-post which is fitted in the anglebetween the sides A and B above the sill 0. Thus the post D forms abrace between the two sides.

To tie the sides A and B together and to the sill O, a metallic angle Fis used. This is adapted to bridge the joint between the sides and thesill O and is provided with a series of apertures a and b, respectively,upon opposite sides of the joint between the side boards and the sill.These apertures provide for the passage of securing pins, nails, orscrews G. The angle F is so arranged that the apertures a are spacedfrom the joint sufficient distance to provide a firm hold for the nailor screw without danger of splitting the block. Inasmuch, however, asthe sides A and B are formed of very thin material, the aperture 1),even if registering with the center line of the sides, would be so closeto the opposite edges as to endanger splitting. I have thereforeovercome this difliculty by arranging the a erture I) very close to theinner face of t e side, so as to leave considerable material between thefastening-nail and the outer face of the side. The outer edge of theangle F is then provided with a flange 0, preferably notched to form aseries of points, and these are driven into the wood of the sides A andB. These points being very thin will not split the sides, but willnevertheless obtain a firm grip upon the latter, so as to clamp them tothe sill O and prevent splitting by the screws or nails G engaging theapertures b.

With the construction as above described it will be observed that thereis nothing to mar the appearance of the body in the way of an exposedjoint or angle at the corner, and at the same time the strength of themetallic angle F is imparted to the corner-joint.

I/Vh at I claim as my invention is 1. In a carriage-body, thecombination with adjacent sides, of a block fitting the inner faces ofsaid sides at the corner, and a metallic angle bridging the jointbetween said block and sides around the corner, being provided withapertures for securing devices on opposite sides of said joint, and withits outer edges turned notched and embedded in the edges of the sides,and securing devices passing through said apertures into the sides andblock.

2. In a carriage body, the combination with adjacent sides, of afilling-block engaging the angle between the inner faces of said sides,of a metallic angle F having the turned outer flanges c, and the doubleseries of apertures a and b, said angle being arranged to bridge thejoint between the sides and block, and securingpins passing through saiddouble series of apertures and respectively engaging the block and thesides, and the flanges a being embedded in the edges of the sides, thepins in said sides being arranged near the inner faces thereof betweensaid inner faces and said embedded flanges.

3. A metallic angle for box-corners, comprising an L-shaped plate havingits outer edges turned to form flanges and notched to form a series ofpoints and a double series of apertures for the securing nails orscrews, substantially as and for the purpose set forth.

4. A carriage-body, comprising a sill, side IIO and end panels adjoiningeach other, and secured'respectively to the side and end of said sill,and a metallic angle bridging the joint between said sides and sill' atthe bottom thereof, being provided with notched flanges for embedding inthe sides and end a seriesof apertures between said flanges and the lineof joint with the sill, a second series ofapertures in the portionunderlapping thesill, and securing-pins engaging said apertures andembedde in the sides and sill. I

I 5. In a carriage-body, a sill formed of hard wood, thin side and endpanels of soft wood adjoining each other, and secured respectivelytovthe sides and end of said sill, an L- shaped metallic angleunderlapping the joint between the panels and sill, being providedembedding in with projecting points at its outer edge for tures betweensaid points and the line of joint with the sill, a second series ofapertures in the portion underlapping the sill, securingpins engagingthe latter series for fastening the angle to said sill, andsecuring-pins engaging the first series and embedded in said panels, thelatter being held from splitting by the embedded points of said angleand the securing of thesarne to the sill.

In testimony whereof I affix my signature in presence of two witnesses.
